Smith recommends reseeding lawns in the fall to prevent weed growth. Since many weeds are already dead late in the season, there is less competition for space as grass seeds try to take root. Smith also recommends strong, high-quality grass seed. Look for the highest germination and purity percentages available.
A rototiller is generally recommended for yards greater than 300 square feet. Its rotary tines break up the lawn and churn the soil as you guide it in the right direction. Gas-powered rototillers tend to be noisier than electric rototillers, which are plugged in and conveniently start at the push of a button.
The bone above the rotator cuff (the point of the shoulder) is called the acromion. Many people with bursitis of the shoulder have a bone spur that forms on the undersurface of the acromion. Depending on the bone of the acromion, a burr may be used to remove the spur to create more space for the rotator cuff tendons.
